Half Hourly Electricity: A Full Breakdown

Posted on Jun 2, 2016

Every day in the energy market things are changing, it can get a little frustrating from time to time trying to keep up with the new rules and regulations. We don’t want you to feel left in the dark regarding half hourly meters. Therefore we have tried to break it down as best we can to hopefully ease your mind.

Essentially, sites with a pinnacle load above 100kW are required to be introduced to a half hourly (HH). Half hourly meters can also be referred to as 00 meters. HH record data from consumption every 30 minutes – this information is communicated to the Supplier.

Half hourly meters can be found in a stretch of economic sites

Ranging from call centres, manufacturing sites, supermarkets all the way to sites which consume as much as places like Manchester Airport, half hourly meters can be found everywhere! Over 160, 000 sites are affected by this so it is definitely worth checking if you are part of this large number, further explanation on finding out how can be found below. If your site requires a HH it is vital you have a Meter Operator (MOP).

MOP is an organisation in the energy industry who hold the responsibility for installing and maintaining electricity and gas meters. They also provide the technical meter details to the Data Collector to enable collection of consumption data.

A HH Data Collector is in charge of collecting HH consumption data from the meter. The data is then certified and passed to the supplier for billing. HH meters allow you to understand your consumption and provides you with a reliable source of information for your businesses energy management. What more could you ask for? HH meters can be a great way to save your business money for other beneficial investments.

Finding out if you have a HH meter is easy. All you have to do is check the number next to your supply number marked ‘S’ – if the number reads 00 then you have a half-hourly meter.

Pricing for HH can vary. The following charges may appear on your bill if you have a HH Meter:

Energy Charges: based on your usage, usually split between day and night. Once you are on a HH meter, you should never receive an estimated bill. This is measured in kWh.

Capacity Charges: this charge relates to the Available Capacity for your site. The Average Capacity is the demand for your site which is agreed with the Distribution Network Operator (DNO) and they ensure this is available to you.

Reactive Power Charge: this is the difference between the working power and the total power consumed. If a site has a high reactive power, more current has to flow to provide the same output. This means more capacity has to be provided, potentially increasing costs for DNO.

We have seen a recent increase of our prospective customers signing letters of authority known from within the industry as LOA’s. Letters of authority enable third parties such as energy brokers and consultants to collect data so a gas or electricity quote can be offered. However we have seen an increasing number of brokers and consultants not only offering gas and electricity quotes, but will go as far as to change your supply to another provider without any further consultation and not informing the end user of any prices. We strongly advise customers to thorughly check the content of any Letter Of Authority which is signed. This document is important because under the Data Protection Act you have a right to confidentiality. Be careful that Letters of authority do not mention “the right to change supply” as this could lead to higher bills with out the end user being aware.

Should you smell gas or suspect there has been a leak of other fumes such as carbon monoxide you should call the free 24 hour national emergency number on 0800 111 999 immediately. It is the responsibility of your gas distributor to make your property safe but the following will outline what precautions you should take after you have called 0800 111 999 and then what steps need to be taken after the engineer has visited.
Natural Gas
If you are able to smell gas then please ensure you follow these steps:
Call the national emergency number on 0800 111 999
Do not use your mobile phone to make this call if you are in the property where there is a suspected gas leak. If your only option is to use a mobile phone then make the call either outside or in a neighbouring property
Open all doors and windows
Never use matches, lighters or any other type of naked flame
Do not smoke
Do not switch any electrical appliances on or off, this includes doorbells and lights
Ensure that the gas supply to any appliances has not been left on and that the pilot light on any boilers has not gone out
If you know how to and feel comfortable doing it then turn off the gas supply at the meter
It is not your responsibility to fix any gas leaks at your property, this is the responsibility or your gas distributor and once you have reported the leak through the national emergency number they will visit your property free of charge. Make sure the engineer is a Gas Safe registered engineer and request to see the necessary documentation confirming this.
If the leak is in a domestic property they may be able to make it safe by switching off the gas supply. Provided they are able to the gas engineer will fix the leak there and then, if not they will isolate the faulty appliance and switch the gas back on if it is safe to do so.
Once the engineer has completed all the work they are able to they will leave all the relevant information concerning who to contact should any repairs need to be made. If the fault is with the distribution company and you are left without gas for more than 24 hours you will be entitled to compensation. You will need to contact your supplier should this apply to you.
Carbon Monoxide
A carbon monoxide leak is just as dangerous as a natural gas leak, though it is not combustible like natural gas it is poisonous and restricts your bloods ability to transport oxygen around your body. However, it is much more difficult to notice as carbon monoxide is colourless and odourless but there are indicators to look out for:
Flames on gas appliances burn orange or yellow instead of blue
There is undue condensation on your windows
There is visible soot or a scorched look on any gas appliances
The pilot light on any of your boilers frequently goes out
The easiet possible way is to invest in a carbon monoxide detector, the Gas Safe Register states the following on their website:
“Gas Safe Register recommends the use of audible carbon monoxide alarms. It should be marked to EN 50291 and also have the British Standards’ Kitemark or another European approval organisation’s mark on it. CO alarms usually have a battery life of up to 5 years. Fit an alarm in each room with a gas appliance. Always follow the alarm manufacturer’s instructions on siting, testing and replacing the alarm. Do not use the ‘black spot’ detectors that change colour when carbon monoxide is present, they don’t make a sound. It is important to choose an alarm that will wake you up if you’re asleep, or you may not be aware of early CO symptoms until it is too late.”
If you suspect there is a carbon monoxide leak or your carbon monoxide alarm has alerted you to one then you must:
Leave the property immediately
Call national emergency number on 0800 111 999
If any from the property is displaying any of the following symptoms seek urgent medical attention as they may be suffering from carbon monoxide poisoning:
headaches
dizziness
nausea
breathlessness
collapse
loss of consciousness
Turn off any appliances and do not switch them back on until they have been checked
Ensure that any and all repairs are completed by a Gas Safe registered engineer
Following these steps will help to ensure the safety of anyone at a property affected by either a natural gas leak or carbon monoxide leak. As a matter of precaution make sure the national emergency number is kept somewhere prominent in the property so that it can be found by anyone in the event of any kind of leak and that any residents or employees at the property are aware of the above.
